   3. injure its ears

   4. jump out of your arms

   5. reflexively defecate and urinate

6. In a calf that died from severe diarrhea associated with high serum pepsinogen levels, necropsy reveals the rumen, reticulum, and omasum to be full of feed, while the remainder of the alimentary tract is virtually empty. The mucosa of the abomasum is covered with gray-white, 3- to 5-mm nodules, each of which contains a small worm. What is the parasite responsible for this type of lesion in cattle?

   1. Hemonchus placei

   2. Trichostrongylus axei

   3. Ostertagia ostertagi

   4. Nematodirus helvetianus

   5. Bunostomum phlebotomum

7. The owner of a 5-month-old quarter horse foal with respiratory distress treats the animal for about a week with ampicillin. The foal develops diarrhea just before dying. Necropsy reveals extensive abscess formation in the lungs and bronchial lymph nodes. Abscesses and ulcerations are also present in the small intestine. You isolate a gram-positive, catalase-positive bacterium from the lesions. What is the most likely cause of these findings?

   1. Bordetella bronchiseptica

   2. Listeria monocytogenes

   3. Rhodococcus equi

   4. Streptococcus zooepidemicus

   5. Streptococcus equi

8. The kidney is a complex organ comprised of capsule, cortex, medullary pyramids, pelvis, and pelvic diverticula. Which of the following best describes the relative echogenicity of the cortex, medullary pyramids, and pelvis/pelvic diverticula, from the most hyperechoic to the least hyperechoic? Assume that the kidney is normal and that the animal is not undergoing physiologic diuresis.

   1. cortex > medullary pyramids > pelvis and diverticula

   2. pelvis and diverticula > medullary pyramids > cortex

   3. pelvis and diverticula > cortex > medullary pyramids

   4. medullary pyramids > cortex > pelvis and diverticula > cortex

   5. The kidney has a uniform hypoechoic appearance, with differences in echogenicity seen only with pathologic changes.

9. In a cow, clinical signs of acute mastitis caused by a gram-negative organism include all of the following except:

   1. complete anorexia

   2. rumen stasis

   3. bradycardia

   4. swollen mammary gland

   5. fever of 40.5°C (105°F)

10. Phenothiazine is one of the oldest drugs available for:

    1. treatment of mastitis in sheep and goats

    2. prevention of urolithiasis in lambs

    3. use as a feed additive to prevent coccidiosis in lambs

    4. treatment of nematode infections in sheep

    5. estrus synchronization in ewes
